since upgrading my vaio notebook to Ubuntu 11.10, I am unable to scroll using my trackpad. Tried all means to no avail. Please suggest a step by step process to solve the problem. This has almost left me regretting the upgrade.

looking forward to replies

Try this:

sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps

It should works now. It's time to make it permanent:

sudo tee /etc/modprobe.d/psmouse <<< 'options psmouse proto=imps'

That's all.

(That solution was posted here in Ubuntu Jaunty, but it should work in Oneiric)
